Question:

Calculate the radiation dosage (in grays) for a 79 kg person that is exposed for 7.0 seconds to a 3.0 Ci source of beta radiation. Assume that 100% of the radiation is absorbed and each beta particle has an energy of {eq}2.0 \times 10^{-13} {/eq} J.

Radiation:

The term "radiation" may be described as the method by which energy is released from a source and propagated within a surrounding medium. Radiation is the only kind of heat transfer method that can occur in a vacuum.
